The surface action — literally washing a person's mouth with soap — is directly derivable from the constituents, so the phrase is partly compositional. However, its conventional use as a punitive response to swearing is a culturally specific pragmatic meaning that is not fully predictable from the words alone, so a B1 learner who only knows the constituents may not infer the disciplinary sense.
Etymology
Wash someone's mouth out with soap comes from a real punishment parents used: they would put soap in a child's mouth or wash the mouth after the child said bad words. The bitter taste and cleaning were meant to teach a lesson, so the phrase now means 'to punish someone for using bad language'.
